“I wanted it to be the biggest sounding Foo Fighters record ever,” frontman Dave Grohl says of the band’s new music. “To make a gigantic rock record but with Greg Kurstin’s sense of melody and arrangement… Motorhead’s version of Sgt. Pepper… or something like that.”

While performing at the Lucavsala festival in Riga, Latvia the group broke out the previously unheard track “Sunday Rain.”
